In a shocking new development, the FBI announced Friday morning that they are diving back in to Hillary Clinton’s email investigation, due to new emails uncovered.

The FBI has reopened its investigation into Hillary Clinton’s use of a private email server while secretary of state, in a stunning turn of events just days before the presidential election.

FBI Director James Comey wrote in a letter to top members of Congress Friday that the bureau has “learned of the existence of emails that appear to be pertinent to the investigation.”

Comey did not detail those emails, saying only that they surfaced “in connection with an unrelated case.”

He told lawmakers the investigative team briefed him on the information a day earlier, “and I agreed that the FBI should take appropriate investigative steps designed to allow investigators to review these emails to determine whether they contain classified information, as well as to assess their importance to our investigation.”

He said the FBI could not yet assess whether the new material is significant and he could not predict how long it will take to complete “this additional work.”

The move comes after Comey and the Justice Department decided in July not to pursue charges over Clinton’s email practices.

Comey has since come under criticism from lawmakers and others who claim the investigation downplayed the mishandling of classified information during Clinton’s tenure.

“The FBI’s decision to reopen its investigation into Secretary Clinton reinforces what the House Judiciary Committee has been saying for months: the more we learn about Secretary Clinton’s use of a private email server, the clearer it becomes that she and her associates committed wrongdoing and jeopardized national security,” House Judiciary Committee Chairman Bob Goodlatte, R-Va., said in a statement.

“Now that the FBI has reopened the matter, it must conduct the investigation with impartiality and thoroughness. The American people deserve no less and no one should be above the law.”
